General Growth said its biggest debt and equity holders offered to jointly invest $3.93bn in the company, bolstering a plan with Brookfield Asset Management Inc. to bring the mall owner out of bankruptcy.

The investments from Bruce Berkowitz’s Fairholme Capital Management and William Ackman’s Pershing Square Capital Management would allow unsecured creditors to be paid in full with cash, General Growth said in a statement last night. Their funds are in addition to $2.63bn pledged by Brookfield.

The cash payment matches a provision of a competing bid by Simon Property Group, which has offered to buy its biggest competitor for more than $10bn and pay all unsecured creditors.
